Not long ago a friend posted a shot of one of the Nautilus submarines from the 20,000 Leagues Under the Sea ride at Walt Disney World. I rode this ride at Disneyland and was always captivated by it, and am convinced that it would captivate anybody today. (Who cares if they don't know the movie. Most kids haven't read Tom Sawyer, either, but the pirate caves are incredible.) This article from 2004 tells a wild story of the strange demise of this amazing ride.
